FLUE STOPPER OR COVER.

SPECIFICATION forming part of Letters Patent No. 414,328, dated November 5, 1889.

Application filed Februaxy`26, 1889.

.To all whom t may concern:

Be it known that I, JOHN ROEBUCK, a resi= dent of the city of Brooklyn, Kings county, NewYork, have invented an Improved Flue Stopper or Cover, of which the following is a specification.

This invention relates to Stoppers or covers that are placed over fine-openings in chimneys and tire-boards; and it has for its obj ect to improve the means for holding the stopper or cover over the opening.

The invention consists in the details of improvement and the combinations of parts that will be more fully hereinafter set forth.

Referenceis to be had to the accompanying drawings, forming part of this specilication, in which- Figure l is a face View of my flue cover or stopper; and Fig. 2 is a back view of the same, showing` the means for holding it over the flue-opening. Fig. 3 is a cross-sectional view of the iiue stopper or cover, showing the manner of holding the stopper over the flue-opening in the chimney. Fig. 4 is a similar view showing the stopper as covering the opening in the board of a fire-place; and Fig. 5 is a detail view, enlarged, of part of the flue-stopper.

In the accompanying drawings, the letterA represents a flue stopper or cover which consists of a plate of metal or the like of suitable size and outline, which plate maybe decorated in any manner desired on its face, while on the back the means for retaining the cover in the iiueare carried.

a is a small plate that is or may be carried by the stopper A on its outer side, which plate a may have any suitable ornamentation.

B B are two springs that are carried by the stopper A, which springs may be flat or round in crosssection. The springs B in their normal condition extend along the inner face or side of the flue-stopper A, and they are connected to said stopper by a sleeve D,that is carried by said stopper, the ends of the springs B being passed into said sleeve and overlapped, as shown in Fig. 3.

The sleeve D consists of a metal strip bent to the proper size in cross-section to receive the springs B, the ends b of said strip forming lugs, that are passed through an opening in the cover A and then bent over and laid in line with the face of the fine-stopper A, as

Serial No. 301,185. (No model.)

shown in Fig. 5. By this means the sleeve D is kept from turning and is also held upon the flue-stopper; but the springs B may be carried by the flue-stopper in any other suitable inanner.

The springs B are of the following construction After leaving the sleeve each spring is bent outward toward the plate A, as at c, so as to touch the plate A, or nearly so, and its end is then curled inward, as at f. The springs B, by being curved as shown at c, are adapted to be turned backwardly from the position shown in Fig. 4 into that shown in Fig. 3, the curved part e acting somewhat like a springhinge to permit the free ends f of the springs to be swung. By this means when the stop per is to be placed over a flue-opening E the ends of the springs B will be bent inwardly on the point e and passed into the flue until the stopper A rests against the Wall, as shown in Fig. 3, when the outward spring tendency of the springs will press the curved part fof the springs against the inner walls of .the iue, which, being at right angles to the stopper A, receive the ends of the springs, and thereby retain the cover in position. lf the flue-opening E be larger or smaller, the springs B will adapt themselves to the opening, so as to hold the stopper securely in position. The springs may in some cases be moved outwardly or inwardly slightly in' their holding-sleeve D to compensate for the difference in diameter of the iiue-opening when desired.

When the flue-stopper A is to cover the opening in a board F that is placed in front of a iire-place, the springs will be passed through the opening, but will not be bent at the point e. They will in this case extend along the back of the ireboard F, the lireboard thereby coming between the stopper and the springs. The curvature of the springs, as shown, gives a tension, which, by pressing against the iire-board, holds the iiuestopper in position.

It is evident that instead of having two separate springs B, one double spring of the same character, that extends on both sides of the holding-sleeve D, may be used with the same results.

Having now described my invention, what I claim is-m 1. The Hue-stopper A, combined with the IOO being curved outward at e into contact with the stopper A, and curved backward at the ends at f, and thus enabled to be bent inwardly to press against a Wall at right angles to the stopper, and also adapted to press against a Wall that extends in line with the stopper, substantially as described.
